Relationship management has attracted much attention from academics and practitioners since the 1990 s，especially in business-to-business relationships（Ganesan，1994；Morgan and Hunt，1994）. Guanxi，the Chinese version of relationship management or business networking，has been a growing research interest in recent years（Davies et al.，1995；Lovett et al.，1999；Standifird and Marshall，2000；Wang，2007；Yau et al.，2000）. Guanxi is translated as those personal connections or relationships on which an individual can build to secure resources or draw benefits when doing business as well as in the course of social life（Davies，1995）. Both the direct and indirect relationships of a person build up his/her multilayer guanxi network. Guanxi is crucial to the attainment of long-term business success in China（Yeung and Tung，1996）. Guanxi-based transactions show transaction cost advantages（Standifird and Marshall，2000）. Guanxi has direct and indirect impacts on accessing new markets，finding new customers；building trusting buyer-seller relationships，and enhancing transaction-specific investment behavior. Ultimately，guanxi networks may contribute to firm performance.
